ZF 4681.054.002 4 BP 210 BASICPOWER Transmission Assembly | Complete Unit

Overview

The ZF 4681.054.002 4 BP 210 BASICPOWER Transmission Assembly is a complete, ready-to-install unit engineered for the BP 210 series. This assembly serves as the central power transfer module within the transmission, integrating the planetary gear sets and hydraulic control systems to deliver reliable torque conversion and gear selection. As a full assembly, the SKU 4681.054.002 replaces the entire internal rotating and stationary component group, eliminating the need for piecemeal rebuilding. It is designed to restore original ZF performance in medium-duty commercial and off-highway vehicles, ensuring seamless engagement and consistent power delivery under load.

Symptoms of Failure

When the ZF 4681.054.002 assembly begins to fail, operators typically notice delayed or harsh gear engagement during shifting, especially when moving from neutral to drive or reverse. Another common symptom is intermittent loss of drive power under acceleration, where the transmission slips out of gear without warning. Contaminated transmission fluid with metallic debris is a clear indicator of internal wear within the assembly. Additionally, unusual whining or grinding noises from the transmission housing often accompany bearing or clutch pack degradation, signaling the need for immediate replacement of the complete unit.

Technical Specifications

Compatibility

This complete assembly is specifically designed for the ZF BP 210 series transmissions. It is directly compatible with models including the WG180, WG200, and WG210 series used in construction and agricultural machinery. The unit also fits select ZF 4 BP 210 variants found in forklifts and telehandlers. For proper installation, this assembly must be paired with the TRANSMISSION HOUSING, the HOUS.FRONT SECT, and either the HOUSING REAR PART or the HOUSING REAR SECTION to complete the full transmission casing.

Frequently Asked Questions

Q: Is the 4681.054.002 a direct bolt-in replacement for all BP 210 transmissions?
A: Yes, this complete unit is designed as a direct replacement for the ZF BP 210 series. However, you must verify that your transmission housing sections—specifically the HOUS.FRONT SECT and HOUSING REAR PART—are compatible with the assembly’s mounting flange pattern.

Q: What is the typical lifespan of this assembly under normal operating conditions?
A: With proper maintenance and clean fluid, the ZF 4681.054.002 assembly typically lasts between 8,000 and 12,000 operating hours. Premature failure often results from contaminated fluid or worn housing components like the TRANSMISSION HOUSING.

Q: Can I install this assembly without replacing the fixing plate or screen sheets?
A: While not mandatory, we strongly recommend replacing the FIXING PLATE and both SCREEN SHEET units (4657301032 and 4657301033) during installation to prevent debris from damaging the new assembly.
